It was the official laptop for Harvard Business School\u2019s Master\u2019s program in 1988, beating out IBM for the contract.<\/li>\n\n\n\n<li>OEM for HP: Zenith\u2019s Supersport 286 was rebadged and sold by Hewlett-Packard as the Vectra LS\/12, marking a rare instance where HP sourced laptops from another manufacturer due to Zenith\u2019s superior performance and features at the time.<\/li>\n\n\n\n<li>No Real-Time Clock: Unlike many later laptops, the ZWL-184-02 lacked a hardware real-time clock (RTC); users had to enter the date and time at each boot, a quirk noted by collectors.<\/li>\n\n\n\n<li>Nicknames &amp; Reputation: Sometimes referred to as a &#8220;luggable&#8221; due to its substantial weight (over 13 lbs), it was praised for its robust build and reliability. The keyboard is remembered for its satisfying, clicky feel.<\/li>\n\n\n\n<li>Battery Life Oddities: With two floppy drives, the system could run for up to 4 hours on battery, but with a hard drive installed, battery life dropped sharply\u2014an early example of the trade-offs in laptop design.<\/li>\n\n\n\n<li>Union-Made: Zenith claimed the Supersport was the only union-manufactured personal computer in the world at the time, assembled in Michigan by United Steelworkers<\/li>\n<\/ul>\n\n\n\n<p><strong>Donated by<\/strong>: Dr. Arlen Michaels<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/carleton.ca\/scs\/vintage-computing\/item\">Vintage Computing Collection<\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Zenith Supersport [Vin87] The Zenith Supersport ZWL-184-02, released in 1986, was a rare and advanced &#8220;luggable&#8221; laptop notable for its 4.77 MHz 8086 processor, 20 MB hard drive, electroluminescent backlit CGA LCD display, and robust MS-DOS compatibility.
